UTILIZING LEDs AS FEEDBACK SENSORS FOR VIDEO DISPLAYS

The purpose of this project was to demonstrate as a proof of concept that LED emitters within outdoor video displays can also be utilized as optical feedback sensors for self-calibration. The emission and sensing characteristics of new and degraded LEDs were measured and studied to determine the effectiveness of using LEDs as sensors. A small-scale, adjustable LED driver with a closed-loop feedback control system was designed to illustrate self-calibration without extra sensing components. LED current was automatically adjusted to maintain proper LED brightness and color, while utilizing an adjacent LED as a sensor. Test results show that the self-calibration control system is viable and effective. Further work is necessary to determine system proficiency for large scale LED video display

Divertimi: A Tourist Guide to a Unique and Enriching Experience

This project lays a foundation for the development of an e-tourism website by Azienda di Promozione Turistica della Provincia di Venezia, the provincial tourism authority in the Veneto region of Italy. Our design employs individual and group profiling to recommend destinations and attractions. Social networking and various forms of user-generated narratives support travel recommendations. Finally, we propose a system for offering a personalized trip package based on user interests
